More and more we're aware of IP Telephony. And wi-fi IP Telephony is present now as an alternative for companies to deploy a wireless means of communication - take your desk telephone with you, by using the wi-fi infrastructure rolled out by your company. And when outside, use a wi-fi hotspot to communicate.
MS Portrait runs on local area networks, dialup networks and even wireless networks with bandwidths as low as 9.6 kilobits/second. Microsoft Portrait delivers portrait-like video if users are in low bandwidths and displays full-color video if users are in broadband. In low bandwidths, portrait video possesses clearer shape, smoother motion, shorter latency and much cheaper computational cost than do conventional video technologies. Microsoft Portrait pursues providing presence notification, chat/voice/video functions anytime, anywhere, on any device.
